Electrotome pen with suction function

Abstract

The invention relates to the technical field of medical instruments, in particular to an electrotome pen with a suction function. The electrotome pen comprises a tool bit, a suction tube and a mounting assembly, and the tool bit is arranged on the tube wall of the suction tube and suitable for cutting tissue; the mounting assembly comprises a shell and an insulating sleeve, and the insulating sleeve is arranged on the suction tube in a sleeving mode, arranged between the shell and the tool bit and suitable for wrapping the suction tube. The electrotome pen further comprises an electric control unit and an anti-blocking assembly, and the electric control unit is installed on the shell, makes contact with the suction tube and is suitable for controlling the magnitude of current on the suction tube. The anti-blocking assembly comprises a conduction hose and an extrusion unit, the conduction hose is arranged at the end, opposite to the tool bit, of the suction pipe and communicates with the suction pipe and the corrugated pipe, and the extrusion unit is suitable for extruding the conduction hose under the action of external force. Through cooperative use of the conduction hose and the extrusion unit, the problem that in the prior art, after an electrotome pen sucks large tissue or blood clots, the large tissue or blood clots are attached to the inner wall of a suction tube, and consequently the suction tube is blocked is effectively solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an electric knife pen with a suction function. Background technique [0002] High-frequency electric knife (high-frequency surgical device) is an electrosurgical instrument that replaces a mechanical scalpel for tissue cutting. It heats the tissue when the high-frequency high-voltage current generated by the effective electrode tip contacts the human body, and realizes the separation and coagulation of the tissue, thereby achieving the purpose of cutting and hemostasis. [0003] In the process of using an electrosurgical pen for surgery, it is usually accompanied by cauterization and carbonization of the patient's tissue, as well as the gasification of the patient's body fluid and blood. These high-temperature processes generate large volumes of surgical fumes. [0004] On the one hand, surgical smoke will reduce the clarity of the surgeon's view of the patient's tissue...

AI Technical Summary

Problems solved by technology

[0006] The present invention provides an electric knife pen with a suction function to solve the problem that the electric knife pen in the prior art is easy to suck in large pieces of tissue or blood clots during the suction process, which leads to the blockage of the suction tube of the electric knife pen
